Upgraded the latest driver (v 15.10.5.1) and pro-set software (16.10.0.0). Am now having more limited connectivity issues from the wireless card that I have to use my wired connection to access the internet. I have tried every trick that has been suggested on other forums and everything but nothing seems to be helping this situation. Looking for support as this has been going on for a while and not getting better but worse.

It seems you have a mismatch in the driver version. The latest Intel® Proset Wireless Software for this adapter is 16.11.0. The driver version itself varies depending on the operating system used; please refer to the respective table in the article below.

I uninstalled the driver and removed it from the computer, restarted and it picked up an older driver on the computer. I uninstalled it an deleted it as well. I did this about four times until I got to the Microsoft driver that I couldn't delete. I uninstalled this driver then installed the driver you wanted me to download. Driver 15.12.06 dated Feb. 25, 2014 is installed as well as the Pro Set Software. Within 15 minutes of installing the driver I had limited connectivity. I reset the adapter and again in about 15 min I had limited connectivity. I re-booted the computer and within 5 min had limited connectivity. I just went back into the driver advanced settings and turned off the power saving features. After 30 minutes I was back again to limited connectivity. This process has been very frustrating to me as I replaced my original wifi card with this one to improve the performance. When the card is working, the performance is good. Dropping the signal is not.

The original wireless adapter was a Broadcom 42143 in a Sony Viao Fit laptop computer. That adapter has had documented issues of slow downloads and poor signal strength. My understanding is Sony wasn't providing answers to owners so the recommendation was to change it out to an Intel version. The Intel card has great performance and has great signal strength but looses the default gateway more than an individual would like.

My router is an apple airport extreme and I always keep the router's firmware up to date. This is not the current generation of airport extreme but the 802.11n version before.

I haven't seen any change in the status of the driver in the device manager when the disconnection occurs but will keep an eye out to see if there is any change.

I am testing the computer on a different wireless connection this weekend as we have traveled to a different location. I will report how often the computer looses the connection.

What happens is that we are unable to guarantee optimal performance or connection stability with this type of integration. I would recommend asking the system manufacturer for a list of validated wireless adapters for your computer.
